1. switch off your phone, remove your battery and sim and sd card,
2. reinsert battery and switch on.
3. now make a custom reset by typing this to your keypad *2767*2878#
4. if custom reset doesn't work, then make a hard reset by typing this to your keypad *2767*3855#

take care.

On my 50D error 99 kept coming up to, but upgrading to latest firmware fixed the problem. I'm not sure if this your problem, but try Googling more information.

Try different SIM. If same problem occurs even if you use a known working SIM. Then, the problem has something to do with the RF antenna inside the phone. This needs repair.

I would suggest to contact the dealer for free repair if the phone is still under the warranty.

Have a great day!

For your model .

If you just bought it and you have check the signal source and its ok contact auth Samsung serv company. Samsung has 1 year parts and labor warranty. Some retailers will exchange it if it's you just bought it.

all you need to do is put a original simcard that came whit t phone so if it was locked to o2 and you unlocked the phone then all you have to do is put a o2 sim in it an walla the internet works without a problemhe

1. Since my problem (Samsung/Comcast) began with a channel selection button pushed on the TV remote when it should have been pushed on the cable remote, I figured the problem lay with the TV.  Although I was getting the "weak or no signal" msg., the actual signal strength bar graphic showed it to be strong. Disconnecting did no good. I surmised that the TV was simply not recognizing the box.
2. I looked at the manual for my Samsung 750 model. 
3. Page 20 discussed "Selecting the source". I accessed the TV menu and selected "Input", then chose the "HD..." item from the highlighted list. Voila! My tv works again.
